Ex-Aurora high school teacher gets 6 years for sex assault against student

A former teacher at an Aurora high school was sentenced to 6 years in prison today after pleading guilty to sex assault charges involving a student, according to the DuPage County State’s Attorney’s office.

Robert C. Smith, 28, of Mokena, pleaded guilty to criminal sexual assault involving the student at Metea Valley High School, where he was a physics teacher.

According to authorities, Smith confessed that on at least two occasions he took the female student to a Naperville motel for sexual contact.

He was arrested in October 2010 and had been held in the DuPage County Jail in lieu of $300,000 bail. Officials in his school district placed Smith on leave after his arrest.

Smith must serve at least 85 percent of his sentence. He will also have to register as a sex offender after he completes his prison sentence.
